This is not saying that every hackintosh install is a lost computer sale for Apple. It just means that overall Apple's sales would be higher, even if only one in 10'000 of hackintosh users is dissuaded from buying a Mac.

If it wasn't for if, I'd be the king of Persia. Overall Apple's sales could be higher because of hackintoshes too, even if only one in 10,000 hackintosh users who try OSX out of curiosity end up buying a Mac which they never would have could they not have found out how OSX is beforehand.

The argument cuts both ways, and in the end Apple makes money from the OSX sale and loses nothing because no-one is taking anything from Apple. No matter how it's sliced, Apple makes money from the deal.

And the world becomes one OSX advocate richer for every successful hackintosh as well.
